12. Preparing the fin
Move the rudder to and fro (about ten to twenty times) to free up
the hinge.
Slip the wire tailwheel unit 68 through the glue-fitting tailwheel
bracket 37, fit it through the glue-fitting horn 36 and use a pair of
combination pliers to bend the end over at 90° as close as
possible to the horn, as shown in Fig. 14.
The horn 36 can now be glued to the rudder, applying cyano only
from the underside. When the glue has set hard, cut a slot about
1.5 mm deep above the horn to accept the tailwheel wire.
Rotate the tailwheel wire 68 over the horn 36, align the tailwheel
unit, and glue the wire to the rudder using plenty of cyano.
Figs. 14 - 15
Mount the swivel pushrod connector on the rudder horn, and
secure the nut with a drop of paint or glue.

13. Glue the fin to the fuselage
Fig. 16
The tailwheel 69 can now be fitted: slip one wheel retainer (tubular
rivet) 70 on the wire, followed by the wheel and the second
retainer. Glue the retainers 70 to the wire using a drop of cyano.
Caution: apply small drops of glue on the tip of a small
screwdriver or similar. Please don't glue the wheel to the axle!

14. Preparing the cabane
Remove the cabane moulding 6 (L / R) from the moulding sprue.
Glue the following parts together: 2 x 6 (cabane), 34 (glue-fitting
screw sleeve) and 7 (cabane centre piece).
Fig. 18
15. Decals!
Before you carry out any more work, it makes sense to apply the
decals to the wings, as access will never be as good again!
16. Completing the top wing
Glue the GRP spar 50 in the channel in the underside of the top
wing 11, after checking that the channel is the correct length;
apply the glue to the full length of the spar. Take great care to
keep the wing exactly flat and straight while the glue is curing.
Release the ailerons by cutting along the marked lines at both
ends. Free up the hinges by moving them to and fro repeatedly.
Glue the cabane assembly 6 / 7 to the top wing.
Fig. 19
Trim the wing struts 10 and 9 to fit before gluing them to the
underside of the top wing. Before reaching for the glue, check
that you are fitting the left strut to the left wing (right to right), and
that the struts are the right way up!
Figs. 20 + 21
17. Installing the aileron linkages
Glue the flat link horns 35 in the ailerons of the top wing 11, with
the small 1.6 mm Ø holes projecting.
Fig. 22
18. Completing the bottom wing
Mount the swivel connectors on the aileron horns 24 and glue
them to the bottom ailerons. Repeat the procedure with the flat
link horns 35, but this time with the 2.5 mm Ø holes projecting;
the swivel connectors for the aileron link pushrods are fitted in
these holes.
Fig. 23
Install the servos and the aileron pushrods 30, set the servos to
centre from the transmitter, and adjust the linkages so that the
ailerons are at neutral.
Fig. 24
19. Installing the main undercarriage retainer
The undercarriage retainer 66 is installed in the moulded-in
recess in the bottom wing. Press it into place "dry" first, so that
the projecting tongues are forced into the foam, then simply glue
it in place with plenty of cyano. Glue the wing screw sleeve 34 in
the recess in the bottom wing, again using cyano.
Fig. 25
20. Joining and completing the top and bottom wings
The wing struts can now be glued to the bottom wing.
Fig. 26
Connect the aileron link pushrods 54, fit them through the swivel
connectors at the bottom, and tighten the grubscrews. Check
that all four ailerons are at neutral, then cut the bottom ailerons
free (1 mm gap at both ends).
Fig. 27
21. Preparing the wheel spats (replacement part No. 22 4204)
Glue the holders for the wheel spats 65 into the right and left
outer spat shells 16 / 17. Fit the collets 62 on both sides together
with the 5 mm socket-head grubscrews 64. Join the wheel spats
and glue the inner shells 14 / 15 to the outer shells 16 / 17 using
cyano.
Fig. 28
22. Assembling and installing the main undercarriage
First check the wheel tracking as shown in the drawing, and
correct it if necessary.
Fig. 29
Attach the inner collets 62, and fit the wheels 61 together with the
wheel spat assemblies. Align the parts and tighten the
grubscrews 63 in the outer collets 62 to hold everything in place.
Snap the wire undercarriage unit 60 in the plastic retainer, and
secure it with the screw 67.
23. Provisional final assembly
Gently widen the gap between the wings so that the fuselage fits
between them, insert the fuselage, and connect the aileron servo
leads. Gently prise the bottom wing away from the wing saddle,
and thread the servo connectors into the fuselage. Fix the wings
to the fuselage using the two plastic M5 screws 31.
Figs. 30 + 31
24. Installing the motor
We recommend the use of the Gemini power set, Order No. 33
2634. Attach the motor to the motor bulkhead 40; the end of the
shaft should project beyond the face of the motor bulkhead by 10
mm.
Fig. 32
If the shaft projects more than this (for example, if you are using
a different make of motor) you will need to add packing pieces
behind the motor.
25. Attaching the motor bulkhead to the motor mounts
The motor sidethrust and downthrust can be altered by adjusting
the motor mounts 39 relative to the motor bulkhead 40. The
motor mount is asymmetrical by nature; if the four adjustor screws
41 are fitted flush, the motor is installed with maximum sidethrust
and no downthrust. We recommend the following base set-up;
note that the motor bulkhead is viewed from behind (!).
